Abstract

The invention relates to coach bodywork, in particular for railway coaches for passenger transport. The floor 1, the side walls 2 and the roof 3 are composed of basic profiles 9a, 9b, 9c. They have webs 17 which protrude from the plate 18 and have flanges 20 which have flange faces 21. The basic profiles 9a, 9b, 9c are formed as extruded profiles. Accordingly, the webs 17 run parallel to one another. The webs and the flange faces 21 serve to attach load-bearing covering panels 10. Insulation can be attached between the covering panels 10 and the plate 18 of the basic profile 9b. All the installations, for example electric lines 50, can be initially attached after welding the basic structure consisting of floor 1, longitudinal member 4, side wall 2, upper chord 5 and roof 3 and their basic profiles 9a, 9b, 9c. Subsequently, after the insulation has been fitted, the covering panels 10 can be appropriately attached. A simple and lightweight body is obtained which is entirely self-supporting. <IMAGE>

Description

Die Erfindung betrifft einen Wagenkastenaufbau, insbesondere für Eisenbahnwagen zur Personenbeförderung, mit einem Boden, zwei Seitenwänden, zwei Stirnwänden und einem Dach sowie Öffnungen in den Seitenwänden und/oder Stirnwänden in Form von Fenstern und/oder Türöffnungen, wobei der Boden mit den Seitenwänden durch Langträger und die Seitenwände mit dem Dach durch Obergurte verbunden sind und die Langträger und die Obergurte als Voll- oder Hohlprofile aus einem Aluminiumwerkstoff stranggepreßt sind und parallel zu einer Längsachse, die die Längenerstreckung des Wagenkastenaufbaus darstellt, verlaufen und wobei die Seitenwände Vollprofile mit Stegen aus einem Aluminiumwerkstoff, eine Isolierung und Deckplatten aufweisen.The invention relates to a body structure, in particular for railway carriages for passenger transport, with a floor, two side walls, two end walls and a roof and openings in the side walls and / or end walls in the form of windows and / or door openings, the floor with the side walls by long beams and the side walls are connected to the roof by upper straps and the long beams and the upper straps are extruded as solid or hollow profiles made of an aluminum material and run parallel to a longitudinal axis, which represents the longitudinal extension of the body structure, and wherein the side walls have solid profiles with webs made of an aluminum material , have insulation and cover plates.

Ein solcher Wagenkastenaufbau ist aus der EP 0 148 123 A2 bekannt. Nachteilig bei dieser Ausbildung ist, daß der Wandaufbau aus einer innenliegenden Tragstruktur und einer nichttragenden Außenhaut besteht. Hiermit ist ein erhöhter Platzbedarf gegenüber einer konventionellen Konstruktion verbunden. Der Innenraum der Fahrgastzelle verkleinert sich, da die äußeren Fahrzeugabmessungen gleich bleiben müssen. Zudem erhöht sich das Gewicht des Fahrzeuges, da zusätzlich zu der Tragstruktur eine zweite, nur dekorativen Zwecken dienende Struktur eingebaut ist.Such a body structure is known from EP 0 148 123 A2. A disadvantage of this design is that the wall structure consists of an internal supporting structure and a non-supporting outer skin. This is associated with an increased space requirement compared to a conventional construction. The interior of the passenger compartment is reduced in size since the outer vehicle dimensions must remain the same. In addition, the weight of the vehicle increases because, in addition to the supporting structure, a second structure is used, which is only used for decorative purposes.

Es ist auch üblich, einen Wagenkastenaufbau aus Blech und Aluminiumstrangpreßprofilen oder Stahlprofilen herzustellen, welche unter anderem auch die Außenkontur des Fahrzeuges bestimmen. Neben der heute üblichen Blech-Gerippe-Bauweise für Stahlfahrzeuge, die einen sehr hohen Richtaufwand zur Erzielung einer möglichst ebenen Außenfläche zur Folge hat, ist auch bei einer Aluminiumintegralbauweise die Oberflächenqualität nicht immer so gut, wie eigentlich gewünscht. Offene Strangpreßprofile werden dabei durch senkrecht zur Fahrzeuglängsrichtung verschweißte Profile versteift. Durch die Einbringung der Schweißwärme und unterschiedliche Abkühlverhältnisse können sich diese Versteifungsprofile an der Fahrzeugaußenhaut abzeichnen. Ohne Verwendung von Spachtelmaterial, auf das aus Kosten- und Gewichtsgründen jedoch in den meisten Fällen verzichtet werden soll, ist eine optisch einwandfreie Oberfläche nur schwer zu erzielen. Falls die Oberflächenqualität bei Verwendung von Hohlprofilen verbessert bzw. ausreichend sein sollte, müßten aber immer noch die Längsschweißnähte, die die Aluminiumstrangpreßprofile miteinander verbinden, abgearbeitet und verputzt werden. Dies bedeutet ebenfalls einen erhöhten Zeit- und Kostenaufwand. Bei leichten Kollisionen und bei anderen Beschädigungen wird die Tragstruktur, die im wesentlichen aus den Aluminium-Strangpreßprofilen oder Stahlprofilen besteht, und gleichzeitig auch Außenkontur des Fahrzeuges ist, unmittelbar beschädigt und bedarf einer sorgfältigen Reparatur. Diese Reparatur muß den optischen Ansprüchen wie vorbeschrieben gerecht werden.It is also common to produce a body structure from sheet metal and aluminum extrusions or steel profiles, which also determine the outer contour of the vehicle, among other things. In addition to the usual sheet metal structure for steel vehicles, which results in a very high level of straightening to achieve the most even outer surface possible, even with an integral aluminum construction, the surface quality is not always as good as actually desired. Open extruded profiles are stiffened by profiles welded perpendicular to the longitudinal direction of the vehicle. By introducing the welding heat and different cooling conditions, these stiffening profiles can be seen on the outer skin of the vehicle. Without the use of filler material, which should be avoided in most cases for reasons of cost and weight, it is difficult to achieve an optically perfect surface. If the surface quality should be improved or sufficient when using hollow profiles, the longitudinal weld seams that connect the extruded aluminum profiles would still have to be machined and plastered. This also means increased expenditure of time and money. In the event of minor collisions and other damage, the supporting structure, which essentially consists of the extruded aluminum or steel profiles and at the same time the outer contour of the vehicle, is immediately damaged and requires careful repair. This repair must meet the visual requirements as described above.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Wagenkastenaufbau zu schaffen, der ein möglichst geringes Gewicht aufweist, bei dem der Zusammmenbau einfach gestaltet ist und darüber hinaus optisch einwandfreie Flächen im Sichtbereich erzielt werden können.The invention is therefore based on the object of providing a body structure which is as small as possible Has weight in which the assembly is simple and, moreover, optically perfect areas can be achieved in the field of vision.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Boden, die Seitenwände und das Dach jeweils aus mindestens einem Grundprofil aufgebaut sind, das als Aluminiumstrangpreßprofil gestaltet ist und aus einer Platte mit damit einstückigen, von einer Fläche der Platte vorstehenden Stegen mit Flanschen und Flanschflächen besteht, wobei die Stege parallel zur Längsachse verlaufen, daß die Stege zu den ebenfalls parallel zur Längsachse verlaufenden Längskanten der Platte mit Abstand angeordnet sind und parallel zu diesen verlaufen, daß die Längskanten der Platten unmittelbar oder mittelbar unter Zwischenschaltung von als Strangpreßprofil gestalteten Randprofilen an den Langträgern oder den Obergurten angeschweißt sind, daß die Deckplatten auf den Flanschflächen der Stege einerseits und den Auflageflächen der Langträger oder Randprofile andererseits aufliegen und mit diesen fest verbunden sind und somit zusammen die Tragstruktur in Form eines Hohlprofiles bilden, daß die Deckplatten im Bereich der Seitenwände und des Daches die Außenfläche im Bereich des Bodens die Innenfläche des Wagenkastenaufbaus bilden und daß im Zwischenraum zwischen Deckplatte und Platte Isoliermaterial angeordnet ist.This object is achieved in that the bottom, the side walls and the roof are each constructed from at least one basic profile which is designed as an extruded aluminum profile and consists of a plate with webs with flanges and flange surfaces projecting therefrom from one surface of the plate, wherein the webs run parallel to the longitudinal axis, that the webs are arranged at a distance from the longitudinal edges of the plate, which also run parallel to the longitudinal axis, and run parallel to these, that the longitudinal edges of the plates directly or indirectly with the interposition of edge profiles designed as extruded profiles on the long beams or the upper chords are welded on so that the cover plates rest on the flange surfaces of the webs on the one hand and the support surfaces of the long girders or edge profiles on the other hand and are firmly connected to them and thus together form the supporting structure in the form of a hollow profile, that the cover plates in the area of the side walls and the roof form the outer surface in the area of the floor the inner surface of the body structure and that insulating material is arranged in the space between the cover plate and the plate.

Eine Wagenkastenaufbau mit strangpreßprofile mit einstückigen Stegen mit Flanschen und Flanschflächen ist aus der EP-A-0 379 310 bekannt.A car body structure with extruded profiles with one-piece webs with flanges and flange surfaces is known from EP-A-0 379 310.

Von Vorteil bei dieser Ausbildung ist, daß alle tragenden Grundprofile, Langträger, Obergurte und Randprofile aus Aluminiumstrangpreßprofilen hergestellt werden können, so daß alle Vorteile der Aluminium-Integralbauweise, z. B. Schweißbadstützen, Auflageflächen für Bleche und die Integration von Befestigungselementen genutzt werden können. Ein wesentlicher Vorteil besteht darin, daß auch die Deckplatte mit zur Aufnahme von Kräften herangezogen wird. Die Deckplatte trägt also zur Stabilität des gebildeten Hohlprofiles bei. Durch die nachträgliche Anbringung der Deckplatte wird ermöglicht, den Hohlraum für die Anordnung von Leitungen und auch Isoliermaterial zu nutzen. Es wird also ein günstiges Geräuschverhalten erzielt, ohne daß es des zusätzlichen Aufbringens von Dämmaterialien auf der Innenfläche des Wagenkastenaufbaus bedarf. Hierdurch wird die Größe des zur Verfügung stehenden Wageninnenraumes günstig beeinflußt. Zur Erzielung der festen Verbindung kommen verschiedene Fügeverfahren, z. B. Kleben, Schweißen, Nieten, Schrauben, in Frage.The advantage of this training is that all load-bearing basic profiles, long beams, top chords and edge profiles can be made from extruded aluminum profiles, so that all advantages of the integral aluminum construction, e.g. B. weld pool supports, contact surfaces for sheet metal and integration of fasteners can be used. A major advantage is that the cover plate is also used to absorb forces. The cover plate thus contributes to the stability of the hollow profile formed. The subsequent attachment of the cover plate makes it possible to use the cavity for the arrangement of lines and also insulating material. A favorable noise behavior is thus achieved without requiring the additional application of insulating materials on the inner surface of the body structure. As a result, the size of the available car interior is influenced favorably. Various joining methods are used to achieve the fixed connection, e.g. B. gluing, welding, riveting, screwing, in question.

In Ausgestaltung der Erfindung ist vorgesehen, daß das Dach, der Boden und/oder die Seitenwände aus mindestens zwei Grundprofilen bestehen, die jeweils über ein Mittenprofil verbunden sind, welches als Hohlkammerprofil gestaltet ist und aus einem Aluminiumwerkstoff stranggepreßt ist, wobei die Platten jeweils an einer Längskante mit dem Mittenprofil verschweißt sind.In an embodiment of the invention it is provided that the roof, the floor and / or the side walls consist of at least two basic profiles, each of which is connected via a central profile, which is designed as a hollow chamber profile and is extruded from an aluminum material, the plates each being attached to one Long edge are welded to the central profile.

Von Vorteil hierbei ist, daß über das Mittenprofil eine zusätzliche Versteifung erreicht wird. Je nach Größe des Wagenkastenaufbaus können, zwecks Montage der meist unterflur angeordneten Geräte, vor allem im Boden ein oder mehrere Mittenprofile vorgesehen sein.The advantage here is that an additional stiffening is achieved via the central profile. Depending on the size of the car body structure, one or more center profiles can be provided, particularly in the floor, for the purpose of installing the mostly underfloor devices.

Vorzugsweise verlaufen die Stege vertikal zur Platte des Grundprofils und bilden mit den angeformten Flanschen im Querschnitt eine T-Form. Es ist jedoch auch eine Anordnung möglich, bei der einige der einer Platte zugeordneten Stege mit der Platte einen von 90° abweichenden Winkel bilden.The webs preferably run vertically to the plate of the basic profile and form a T-shape in cross section with the molded flanges. However, an arrangement is also possible in which some of those assigned to a plate Form bridges with the plate at an angle other than 90 °.

Hierdurch wird eine verbesserte Schubsteifigkeit der Gesamtplatte erreicht. Die senkrecht verlaufenden T-Stege sorgen für eine stabile Auflage für die Deckplatte.As a result, an improved shear rigidity of the entire plate is achieved. The vertical T-bars ensure a stable support for the cover plate.

Besonders für die Verwendung des Grundprofiles im Bereich der Seitenwände ist es zweckmäßig, parallel zur Längsachse verlaufende Kammern vorzusehen. Diese können beispielsweise als Luftführungskanäle für die Klimatisierung oder Heizung verwendet werden. In den Bereichen, in denen Austritte zum Innenraum des Wagenkastenaufbaus erforderlich sind, können entsprechende Durchbrüche eingefräst oder eingestanzt werden.Especially for the use of the basic profile in the area of the side walls, it is expedient to provide chambers running parallel to the longitudinal axis. These can be used, for example, as air ducts for air conditioning or heating. In the areas where exits to the interior of the body structure are required, appropriate openings can be milled or punched.

Dabei sind die Wände der Kammer bevorzugt einstückig mit dem Grundprofil gestaltet, d. h. sie können beim Strangpressen des Grundprofils mit hergestellt werden.The walls of the chamber are preferably designed in one piece with the basic profile, i. H. they can also be produced during extrusion of the basic profile.

Alternativ ist es jedoch auch möglich, die Kammer durch ein besonderes Profil zu bilden, welches an der Platte des Grundprofiles befestigt ist. Die Befestigung erfolgt an der Fläche der Platte, von der die Stege vorstehen.Alternatively, however, it is also possible to form the chamber by means of a special profile which is fastened to the plate of the basic profile. It is attached to the surface of the plate from which the webs protrude.

Die Randprofile sind in weiterer Ausgestaltung der Erfindung ebenfalls als Hohlprofile gestaltet und im Strangpreßverfahren hergestellt. Sie dienen zum Toleranzausgleich bei der Fertigung und besitzen im Querschnitt eine dreieckige Grundform mit zwei rechtwinklig aufeinanderstehenden Wänden. Von einer der beiden aufeinanderstehenden Wänden gehen von deren Ecken, die von dieser mit den anderen Wände gebildet werden, zueinander parallele Flansche aus. Diese verlaufen parallel zur Längsachse und dienen zur Verbindung mit entsprechenden Flanschen der Langträger oder Obergurte. Die Verbindung erfolgt durch Schmelzschweißnähte.In a further embodiment of the invention, the edge profiles are also designed as hollow profiles and are produced using the extrusion process. They are used to compensate for tolerances during production and have a triangular cross-section with two walls that are at right angles to one another. From one of the two walls standing on top of each other, the corners of this wall and that of the others Walls are formed from parallel flanges. These run parallel to the longitudinal axis and are used to connect the corresponding flanges of the long girders or top chords. The connection is made by fusion welds.

Zur Verbindung zwischen dem Langträger, den Obergurten, den Randprofilen oder den Mittenprofilen mit den Längskanten der Platten dienen vorzugsweise Rücksprünge, die Anlageflächen bilden. Die Anlageflächen sind so gestaltet, daß eine Schweißbadstütze entsteht. Hierzu ist im Übergang zwischen den beiden Flächen des Rücksprunges eine Rille zur Verbesserung der Schweißnahtqualität gestaltet. Für die Befestigung der Platten sind ebenfalls Auflageflächen an den Langträgern, den Obergurten, den Randprofilen oder den Mittenprofilen vorgesehen. Diese sind im Bereich von Rücksprüngen gegenüber den zugehörigen Außenflächen angeordnet. Der Spalt zwischen den Längskanten der Deckplatte und dem jeweiligen Rücksprung wird zur Abdichtung durch ein Versiegelungsmaterial ausgefüllt. In den Bereichen, die als Sichtflächen gestaltet sind, wird dadurch ein glatter Übergang vom Profil zur Deckplatte erreicht und somit das optische Erscheinungsbild verbessert.Recesses, which form contact surfaces, are preferably used to connect the long girder, the top chords, the edge profiles or the center profiles to the longitudinal edges of the plates. The contact surfaces are designed so that a weld pool support is created. For this purpose, a groove is designed in the transition between the two surfaces of the recess to improve the weld quality. Support surfaces are also provided on the long beams, the top chords, the edge profiles or the center profiles for fastening the panels. These are arranged in the area of recesses opposite the associated outer surfaces. The gap between the longitudinal edges of the cover plate and the respective recess is filled with a sealing material for sealing. In the areas that are designed as visible surfaces, a smooth transition from the profile to the cover plate is achieved, thus improving the visual appearance.

Der Hohlraum zwischen Grundprofil und Deckplatte und insbesondere der zwischen den Stegen, deren Flansche und der angrenzenden Fläche der Platte des Grundprofiles gebildete Kanal kann zur Aufnahme von Installationsleitungen, insbesondere Elektro- , Pneumatik- oder Hydraulikleitungen genutzt werden.The cavity between the base profile and cover plate and in particular the channel formed between the webs, their flanges and the adjacent surface of the plate of the base profile can be used to accommodate installation lines, in particular electrical, pneumatic or hydraulic lines.

Das Grundprofil, das Randprofil oder das Mittenprofil können, da sie als Strangpreßprofile gestaltet sind, zusätzlich mit angepreßten, im Querschnitt eine C- oder T-Schiene bildenden Ausformungen versehen sein, die sich parallel zu den Stegen erstrecken. Diese C- oder T-Schienen können dazu genutzt werden, beispielsweise Aggregate, sofern sie im Außenbereich des Wagenkastenaufbaus liegen, an dem Wagenkasten zu befestigen oder sie können auch bei Anbringung zum Innern des Wagenkastenaufbaues hin, für die Anbringung von Sitzen, Innenraumverkleidungen, Lampenbändern, etc. dienen.The basic profile, the edge profile or the central profile can also, since they are designed as extruded profiles be provided with pressed-in, cross-sectionally forming a C or T rail, which extend parallel to the webs. These C- or T-rails can be used, for example, to attach units, provided they are in the outer area of the body structure, to the body or they can also be attached to the interior of the body structure, for attaching seats, interior panels, lamp strips, etc. serve.

Die Anordnung der Grundprofile soll vorzugsweise so gewählt werden, daß bei einer Seitenwand, die aus zwei Grundprofilen gebildet ist und mit Fensterdurchbrüchen versehen ist, die Schweißverbindung zweier Grundprofile auf halber Höhe der Fensterdurchbrüche angeordnet ist.The arrangement of the basic profiles should preferably be chosen so that in the case of a side wall which is formed from two basic profiles and is provided with window openings, the welded connection of two basic profiles is arranged halfway up the window openings.

Im Bereich der Seitenwände sind die Grundprofile vorzugsweise unmittelbar an den Langträgern und den Obergurten verschweißt. Auf Randprofile kann verzichtet werden, da ein Höhenausgleich nicht erforderlich ist.In the area of the side walls, the basic profiles are preferably welded directly to the long beams and the top chords. There is no need for edge profiles because height adjustment is not necessary.

Vorzugsweise sind im Berich des Daches zusätzliche Randprofile vorgesehen, welche dazu dienen, das Dach mit den beiden Obergurten zu verschweißen und hierbei analog zum Boden die Breitentoleranz des Wagenkastens einzuhalten.Additional edge profiles are preferably provided in the area of the roof, which are used to weld the roof to the two upper chords and to maintain the width tolerance of the car body analogous to the floor.

Besonders günstige Festigkeitseigenschaften ergeben sich, wenn die Deckplatte als Verbundplatte aufgebaut ist. Sie besteht in diesem Fall aus zwei Blechen oder Kunststoffplatten zwischen denen ein Kern ausgebildet ist.Particularly favorable strength properties result if the cover plate is constructed as a composite plate. In this case it consists of two sheets or plastic plates between which a core is formed.

Eine besonders günstige Konstruktion für die Deckplatte ergibt sich, wenn die Deckplatte aus zwei parallelen Aluminiumblechen und einer dazwischen angeordneten gewellten Blechbahn als Kern gebildet ist. Diese Bleche sind unlösbar miteinander verbunden.A particularly favorable construction for the cover plate results if the cover plate consists of two parallel aluminum sheets and an intermediate corrugated sheet metal sheet is formed as a core. These sheets are inextricably linked.

Alternativ ist es möglich, die Deckplatte aus zwei parallelen Kunststoffplatten mit dazwischen angeordneten Schaumkern auszubilden.Alternatively, it is possible to form the cover plate from two parallel plastic plates with a foam core arranged between them.

Die Kunststoffplatten können als faserverstärkte Kunststoffplatten gestaltet sein.The plastic plates can be designed as fiber-reinforced plastic plates.

Eine besonders gute Steifigkeit der gesamte Tragstruktur ergibt sich, wenn die Deckplatten im Bereich des Bodens und Daches in Fahrzeugquerrichtung, d. h. quer zur Längsachse, und in den Seitenwänden ebenfalls quer zur Längsachse, jedoch senkrecht von oben nach unten verlaufend, angeordnet sind.A particularly good rigidity of the entire support structure is obtained if the cover plates in the area of the floor and roof in the transverse direction of the vehicle, i. H. transversely to the longitudinal axis, and in the side walls also transversely to the longitudinal axis, but extending vertically from top to bottom.

Um die Montage der Fensterprofile zu erleichtern, ist in der Ausgestaltung vorgesehen, das Grundprofil mit einer senkrecht zur Grundfläche verlaufenden Nase als Anschlag für das Fensterprofil zu gestalten.In order to facilitate the assembly of the window profiles, the design provides for the base profile to be designed with a nose running perpendicular to the base area as a stop for the window profile.

Besonders günstige Geräuschdämmeigenschaften ergeben sich, wenn entsprechend einer weiteren Ausgestaltung die Fläche der Platte des Grundprofils, aus der die Stege vorstehen und/oder die dieser gegenüberliegende Fläche der Deckplatte mit einer Antidröhnmasse, wie beispielsweise Spritzkork oder spritzbare Mineralfasern, beschichtet sind.Particularly favorable noise insulation properties result if, according to a further embodiment, the surface of the plate of the basic profile from which the webs protrude and / or the surface of the cover plate opposite this are coated with an anti-drumming compound, such as, for example, spray cork or sprayable mineral fibers.

Figur 1 zeigt einen halben Querschnitt eines typischen Wagenkastenaufbaus. Die Hochachse ist mit 6 bezeichnet. Sie bildet die Symmetrieachse für den Querschnitt.Figure 1 shows a half cross section of a typical car body structure. The vertical axis is designated 6. It forms the axis of symmetry for the cross section.

Darüber hinaus ist die Längsachse 7 eingezeichnet. Dies ist die Achse, die sich in die Zeichenblattebene hinein erstreckt und die Längenerstreckung des Wagenkastenaufbaus sowie dessen Fahrtrichtung repräsentieren soll.The longitudinal axis 7 is also shown. This is the axis that extends into the plane of the drawing sheet and is intended to represent the length of the body structure and its direction of travel.

Der im Querschnitt ersichtliche Wagenkastenaufbau umfaßt den Boden 1, der an dem Langträger 4 befestigt ist. Der Langträger 4 erstreckt sich parallel zur Längsachse 7. Er stellt das Bindeglied zwischen Boden 1 und Seitenwand 2 dar. Im oberen Bereich der Seitenwand 2 ist ein Obergurt 5 angebracht, welcher sich ebenfalls parallel zur Längsachse 7 erstreckt und als Bindeglied zum Dach 3 dient. In der Seitenwand 2 ist ein Durchbruch für ein Fenster 8 dargestellt.The car body structure shown in cross section comprises the floor 1, which is fastened to the long beam 4. The long beam 4 extends parallel to the longitudinal axis 7. It represents the link between the floor 1 and the side wall 2. In the upper region of the side wall 2 there is an upper flange 5, which also extends parallel to the longitudinal axis 7 and serves as a link to the roof 3. An opening for a window 8 is shown in the side wall 2.

Figur 2 zeigt eine erste Variante für den Boden 1. Der Boden 1 ist aus einem Grundprofil 9, einer daran angebrachten Deckplatte 10 und einer zwischen beiden befindlichen Isolierung 11 und einem Randprofil 13 und einem Mittenprofil 14 aufgebaut. Zusätzlich ist eine Antidröhnbeschichtung 12 vorgesehen. Das Grundprofil 9 besteht aus einer Platte 18, die mit von ihrer Fläche 19 vorstehenden Stegen 17 versehen ist. Die Stege 17 sind zueinander beabstandet und verlaufen parallel zur Längsachse 7. Sie weisen an ihren Enden Flansche 20 auf, die Flanschflächen 21 bilden. Die Stege 17 und Flansche 20 sind einstückig mit der Platte 18 ausgestaltet und zusammen mit dieser als Strangpreßprofil aus einem Aluminiumwerkstoff hergestellt.FIG. 2 shows a first variant for the base 1. The base 1 is constructed from a base profile 9, a cover plate 10 attached to it and an insulation 11 located between the two and an edge profile 13 and a central profile 14. In addition, an anti-drumming coating 12 is provided. The basic profile 9 consists of a plate 18 which is provided with webs 17 projecting from its surface 19. The webs 17 are spaced apart and run parallel to the longitudinal axis 7. They have flanges 20 at their ends, which form flange surfaces 21. The webs 17 and flanges 20 are designed in one piece with the plate 18 and, together with this, are produced as an extruded profile from an aluminum material.

Die Längskante 22 der Platte 18 des Grundprofils 9 ist mit dem Randprofil 13 verschweißt. Das Randprofil 13 ist als Aluminiumhohlprofil gestaltet und im Querschnitt dreieckförmig aufgebaut. Zwei Wände 27,28 stehen im wesentlichen senkrecht aufeinander. Die Wand 29 verbindet die beiden Wände 27,28. Im Bereich der Ecke zwischen den beiden Wänden 27 und 29 ist eine Anlagefläche 35 an einem Vorsprung vorgesehen. Die Anlagefläche 35 dient zur Auflage der Platte 18 im Bereich ihrer Längskante 22 und weist eine Rille auf, so daß eine Schweißbadstütze zur Anbringung der Schmelzschweißnaht 32 gebildet ist. Von der Wand 28 des Randprofils 13 stehen rechtwinklig Flansche 30,31 unterschiedlicher Länge vor, die zur Auflage an entsprechenden Flanschen 15,16 des Langträgers 4 dienen und mit diesem über Schweißnähte 32 fest verbunden sind. Die andere Längskante 23 der Platte 18 des Grundprofils 9 ist mit dem Mittenprofil 14 verschweißt. Hierzu weist das Mittenprofil 14 ebenfalls einen Rücksprung mit einer Anlagefläche 34 auf, die als Schweißbadstütze gestaltet ist. Mittenprofil 14 und Platte 18 sind durch die Schweißnaht 32 miteinander fest verbunden.The longitudinal edge 22 of the plate 18 of the base profile 9 is welded to the edge profile 13. The edge profile 13 is designed as an aluminum hollow profile and has a triangular cross section. Two walls 27, 28 are essentially perpendicular to one another. The wall 29 connects the two walls 27, 28. In the area of the corner between the two walls 27 and 29, a contact surface 35 is provided on a projection. The contact surface 35 serves to support the plate 18 in the region of its longitudinal edge 22 and has one Groove on, so that a weld pool support for attaching the fusion weld 32 is formed. Flanges 30, 31 of different lengths protrude at right angles from the wall 28 of the edge profile 13, which are used to support corresponding flanges 15, 16 of the long beam 4 and are firmly connected to the latter via welds 32. The other longitudinal edge 23 of the plate 18 of the basic profile 9 is welded to the central profile 14. For this purpose, the center profile 14 also has a recess with a contact surface 34 which is designed as a weld pool support. Center profile 14 and plate 18 are firmly connected to one another by the weld seam 32.

Die den Flanschen 20 zugehörigen Flanschflächen 21 der Stege 17 bilden Auflageflächen für die Deckplatte 10. Die Enden der Deckplatte 10 sind auf Auflageflächen 25 des Randprofils 13 bzw. 26 des Mittenprofils 14 aufgelegt. Die Deckplatte 10 ist mit der Flanschfläche 21 des Grundprofils 9 bzw. den Auflageflächen 25,26 von Randprofil 13 und Mittenprofil 14 durch eine Klebung oder ein sonstiges Fügeverfahren (Nieten, Schrauben, Schweißen) fest verbunden. Die Innenfläche 24 der Deckplatte 10 und die Fläche 19 der Platte 18 sowie die zu dem Hohlraum hinweisende Fläche der Wand 29 des Randprofiles 13 bzw. die entsprechende Fläche des Mittenprofiles 14 sind mit einer Antidröhnbeschichtung 12 versehen. Ferner ist in dem verbleibenden Hohlraum eine Isolierung 11 angebracht. Eine solche Isolierung 11 kann beispielsweise aus Glas- oder Steinwolle bestehen und dient zur thermischen bzw. akustischen Isolierung.The flange surfaces 21 of the webs 17 associated with the flanges 20 form support surfaces for the cover plate 10. The ends of the cover plate 10 are placed on support surfaces 25 of the edge profile 13 and 26 of the center profile 14. The cover plate 10 is fixedly connected to the flange surface 21 of the base profile 9 or the contact surfaces 25, 26 of the edge profile 13 and the center profile 14 by means of an adhesive or another joining method (riveting, screwing, welding). The inner surface 24 of the cover plate 10 and the surface 19 of the plate 18 as well as the surface of the wall 29 of the edge profile 13 pointing towards the cavity or the corresponding surface of the center profile 14 are provided with an anti-drumming coating 12. Insulation 11 is also provided in the remaining cavity. Such insulation 11 can be made of glass or rock wool, for example, and is used for thermal or acoustic insulation.

Figur 3 zeigt eine alternative Gestaltung eines Ausschnittes des Grundprofiles 9a. In Abwandlung zur Gestaltung der Stege 17 gemäß Figur 3 verlaufen einige der Stege 17a geneigt unter dem Winkel W. Deren Flansche 20a und Flanschflächen 21a dienen ebenfalls zur Verbindung mit der Deckplatte 10 z. B. durch Klebung. Durch eine solche Anordnung werden Schubkräfte, die auf den gebildeten Kasten einwirken, besser aufgenommen. Die Vertikallasten, die vor allem bei der Herstellung der Verklebung auftreten, werden unmittelbar durch die rechtwinklig zur Platte 18 verlaufenden Stege 17 aufgenommen.FIG. 3 shows an alternative design of a section of the basic profile 9a. In modification of the design of the Crosspieces 17 according to FIG. 3, some of the crosspieces 17a are inclined at an angle W. Their flanges 20a and flange surfaces 21a are also used for connection to the cover plate 10, for example. B. by gluing. Such an arrangement better absorbs thrust forces which act on the box formed. The vertical loads, which occur particularly during the production of the bond, are absorbed directly by the webs 17 running at right angles to the plate 18.

Figur 4 zeigt eine weitere Ausgestaltungsmöglichkeit für einen Bodenaufbau. Dabei sind jeweils mehrere Grundprofile 9 vorgesehen, wobei jeweils zwischen zwei Grundprofilen 9 ein Mittenprofil 14 vorhanden ist. Die Mittenprofile 14 weisen ebenfalls Anlageflächen 34 auf, die zur Bildung von Schweißbadstützen ausgestaltet sind. Das Grundprofil 9, das benachbart zu dem linken Langträger 4 angeordnet ist, ist mit dem Randprofil 13 im Bereich dessen Anlagefläche 33 durch die Schweißnaht 32 verbunden. Die andere Längskante 23 ist durch eine weitere Schweißnaht 32 im Bereich der Anlagefläche 34 des Mittenprofils 14 mit diesem verbunden. In ähnlicher Weise ist das weitere Grundprofil 9 zwischen zwei Mittenprofilen 14 angeordnet. Im Bereich der der Deckplatte 10 zugeordneten Fläche der im Querschnitt in etwa Trapezform aufweisenden Mittenprofile 14 sind Auflageflächen 26 vorgesehen. Im Bereich des Randprofiles 13 ist eine Auflagefläche 25 dargestellt. Die Deckplatte 10 ist auf diesen Auflageflächen 25,26 aufgeklebt. Dabei ist die Längskante 37 der Deckplatte 10 dem Randprofil 13 und die Längskante 38 dem Mittenprofil 14 zugeordnet. Im Zwischenbereich ist eine Ausgestaltung des Grundprofiles 9 entsprechend der Ausgestaltung gemäß der Figuren 2 oder 3 vorhanden. Unterhalb der Darstellung von Figur 4, die die Bodenkonstruktion zeigt, sind verschiedene Ausführungsformen des Mittenprofiles 14 dargestellt. Das Mittenprofil 14a ist mit zum Innenraum des Wagenkastenaufbaus weisenden T-Schienen 40 versehen. Das Mittenprofil 14a kann ebenfalls als Strangpreßprofil hergestellt werden. Die T-Schienen 40 können beispielsweise zur Anbringung von Sitzen genutzt werden.FIG. 4 shows a further design option for a floor structure. Several basic profiles 9 are provided, a central profile 14 being provided between two basic profiles 9. The center profiles 14 also have contact surfaces 34 which are designed to form weld pool supports. The basic profile 9, which is arranged adjacent to the left long beam 4, is connected to the edge profile 13 in the region of its contact surface 33 by the weld 32. The other longitudinal edge 23 is connected to the latter by a further weld seam 32 in the region of the contact surface 34 of the central profile 14. In a similar way, the further basic profile 9 is arranged between two central profiles 14. In the area of the surface assigned to the cover plate 10 of the central profiles 14, which have an approximately trapezoidal cross section, support surfaces 26 are provided. In the area of the edge profile 13, a support surface 25 is shown. The cover plate 10 is glued to these bearing surfaces 25, 26. The longitudinal edge 37 of the cover plate 10 is assigned to the edge profile 13 and the longitudinal edge 38 to the center profile 14. In the intermediate area there is a configuration of the basic profile 9 corresponding to the configuration according to FIGS. 2 or 3 available. Various embodiments of the central profile 14 are shown below the illustration in FIG. 4, which shows the floor construction. The central profile 14a is provided with T-rails 40 pointing towards the interior of the body structure. The central profile 14a can also be produced as an extruded profile. The T-rails 40 can be used, for example, for attaching seats.

Bei der Ausgestaltung des Mittenprofiles 14b ist neben den nach oben weisenden T-Schienen 40 eine nach unten weisenden C-Schiene 41 vorgesehen. Diese kann beispielsweise zur Anbringung von Antriebsaggregaten außerhalb des Wagenkastenaufbaus genutzt werden. Bei dem Mittenprofil 14c ist lediglich eine außen liegende C-Schiene 41 vorgesehen. Eine Anwendung der Mittenprofile entsprechend der vorbeschriebenen Gestaltungsmöglichkeiten kann auch im Bereich der Seitenwände vorhanden sein. Um einen einfachen Austausch der unterschiedlichen Konstruktionvarianten der Mittenprofile 14,14a,14b und 14c zu gewährleisten, sind deren Konstruktionsbreiten B1 und B2 gleich gewählt.In the configuration of the center profile 14b, a downward-pointing C-rail 41 is provided in addition to the upwardly pointing T-rails 40. This can be used, for example, to attach drive units outside the body structure. In the middle profile 14c, only an external C-rail 41 is provided. The center profiles can also be used in the area of the side walls in accordance with the design options described above. In order to ensure a simple exchange of the different construction variants of the center profiles 14, 14a, 14b and 14c, their construction widths B1 and B2 are chosen to be the same.

Aus Figur 5 ist die Gestaltung einer besonders günstigen Deckplatte 10 zu ersehen. Die Deckplatte 10 besteht aus den beiden parallel zueinander angeordneten Aluminiumblechen 42,43. Diese werden über eine gewellte Blechbahn 44 als Kern auf Abstand zueinander gehalten. Die Blechbahnen 42,43,44 sind fest miteinander verbunden. Es wird somit eine steife Struktur erzielt. Diese Struktur erlaubt jedoch auch ein einfaches Anpassen an einen bogenförmigen Verlauf, wenn die Biegeachse sich parallel zu den Wellentälern 45 erstreckt. Die Anordnung ist insbesondere im Bereich des Bodens 1 so getroffen, daß die Wellentäler 45 sich quer zur Längsachse 7 erstrecken. Eine gleiche Anordnung ist im Bereich des Daches 3 vorgesehen.The design of a particularly favorable cover plate 10 can be seen from FIG. The cover plate 10 consists of the two aluminum sheets 42, 43 arranged parallel to one another. These are held at a distance from one another via a corrugated sheet metal web 44 as the core. The metal sheets 42, 43, 44 are firmly connected to one another. A rigid structure is thus achieved. However, this structure also allows easy adaptation to an arcuate course if the bending axis extends parallel to the wave troughs 45. The arrangement is particularly in the Area of the bottom 1 taken so that the troughs 45 extend transversely to the longitudinal axis 7. A similar arrangement is provided in the area of the roof 3.

Figur 6 zeigt den Aufbau einer Seitenwand 2.FIG. 6 shows the structure of a side wall 2.

Es ist ersichtlich, daß im Bereich des Überganges zum Langträger 4 eine andere Konstruktion des Grundprofiles 9b gewählt ist. Es erfolgt eine Vergrößerung des Freiraumes zwischen der Platte 18b und der Deckplatte 10. Im Bereich eines Steges 17b ist nach innen vorstehend eine L-Schiene 55 angeformt. Der zwischen einem Schenkel des Flansches des Steges 17b und der Fläche 19 der Platte 18 gebildete Kanal 46 kann zur Anordnung von Elektroleitungen 50 ge-nutzt werden. Es ist eine Kammer 47 angeformt, die nach der Herstellung des Strangpreßprofiles in Form des Grundprofiles 9b bereichsweise durch Durchbrüche 48 zum inneren des Wagenkastenaufbaus geöffnet werden kann. Die Kammer 47 kann beispielsweise als Luftführungskanal genutzt werden.It can be seen that a different construction of the base profile 9b is selected in the area of the transition to the long beam 4. There is an increase in the free space between the plate 18b and the cover plate 10. In the region of a web 17b, an L-rail 55 is formed inwards on the inside. The channel 46 formed between one leg of the flange of the web 17b and the surface 19 of the plate 18 can be used for the arrangement of electrical lines 50. A chamber 47 is integrally formed, which after the production of the extruded profile in the form of the basic profile 9b can be opened in areas through openings 48 to the interior of the body structure. The chamber 47 can be used, for example, as an air duct.

Ferner kann das Grundprofil 9b auch so gestaltet sein, daß von der Platte 18b im Bereich der anzubringenden Fenster eine Nase 51 nach innen von der Fläche 19 vorsteht. Diese Nase 51 kann mit angepreßt werden und erleichtert die Montage des Fensters 8 insofern, als ein Hohlkammerprofil 52 hieran angelegt wird, dessen einer Abschnitt als Anlage für eine erste Scheibe 53 dient. Die zweite Scheibe 53 ist bündig mit der Außenfläche der Deckplatte 10 verlaufend angeordnet. Zwischen beiden befindet sich ein Dichtungsprofil 54. Im Übergangsbereich zwischen beiden kann im Spalt 59 eine Versiegelung vorgesehen sein. Aus Figur 6 ist ebenfalls erkennbar, daß die Deckplatte 10 sich über einen Teilbereich des Profiles des Langträgers 4 erstreckt und an einer Auflagefläche 39 desselben verklebt ist. Im unteren Bereich des Langträgers 4 ist ein Vorsprung 57 vorgesehen, zu dem die Auflagefläche 39 zurückversetzt ist. Zwischen der Längskante der Deckplatte 10 und dem Vorsprung 57 ist ein Spalt 59 vorhanden, der durch eine Versiegelungsmasse abgedichtet ist.Furthermore, the basic profile 9b can also be designed such that a nose 51 protrudes inwards from the surface 19 from the plate 18b in the region of the windows to be fitted. This nose 51 can also be pressed on and facilitates the assembly of the window 8 in that a hollow chamber profile 52 is placed thereon, one section of which serves as an abutment for a first pane 53. The second disc 53 is arranged flush with the outer surface of the cover plate 10. A sealing profile 54 is located between the two. In the transition area between the two, a seal can be provided in the gap 59. From Figure 6 it can also be seen that the cover plate 10 over extends a portion of the profile of the long beam 4 and the same is glued to a support surface 39. In the lower area of the long beam 4, a projection 57 is provided, to which the bearing surface 39 is set back. There is a gap 59 between the longitudinal edge of the cover plate 10 and the projection 57, which is sealed by a sealing compound.

Aus Figur 7 ist eine alternative Gestaltung hinsichtlich der Anbringung der Kammer 47 zur Luftführung ersichtlich.
